I'm using a Canon ZR60 to pass-thru capture old 8mm analog. My system setup is a P4 2.4GHz, VIA 1394 card, 1 Gig RAM, second 160 Gig 7200 rpm ATA133 (nothing on it yet) on it's own Maxtor (Promise) ATA133 controller.
When I'm pass-thru capturing, I seem to get a frame drop when the analog video source has sudden motion. This usually only happens about every 10-15 minutes. I tried capturing to DV tape first then transferring and this seems to drop frames more often (every 30-40 seconds).
In pass-thru capture, I can cause frame drops by fast forward and rewind of the 8mm analog source.
I'm confused about all of this. I thought that once the A/D in the camcorder was done with the digitizing that the 1394 transfer was independent. What I'm seeing seems like it's content-specific and can cause dropped frames.
By the way, I've transfered original DV source with no problem.
Do I need a different 1394 card or is there a flaw in the camcorder analog capture or something else?
Sometimes you can run into problems with dropped frames when you use your digital camera for pass-through. That is why we recommend a dv/analog converter such as Datavideo's DAC-100. Check it out here http://www.videoguys.com/dac.html. It's $199.95.
